Questions about Firefox

Here are the details most teams check before getting started.

Is the Firefox workflow different from Chrome?

No. Chrome and Firefox use the same WriteAlt workflow; only the browser installation page changes.

Can I add image URLs manually?

Yes. The extension includes an Add image URLs field for cases where a current page image cannot be selected directly.

Where are recent results kept?

Recent results stay in the extension history on that browser, and you can export them as a CSV.
